Auck vs Wellington Train Performance


In April, 90% of Wellington trains were on time to within 5 minutes in April.  84% of trains were on time to within 3 minutes.
Of the 7,115 Auckland train services scheduled in April, 97.4% arrived at their final destination but only 81.9% were on time -within 5 minutes which is the Veolia measurement of being on time. Unlike Wellington’s Tranz Metro, it uses 5 minutes, not 3 as the standard measurement.

In March 89% of Wellington trains were on time to within 5 minutes  - Only 80% of Auckland’s trains arrived on time (within 5 minutes) that month.

So both cities have seen slight improvements in April.

Auckland Transport has set a train performance target of 85% punctuality (trains arriving at their destination within five minutes of their scheduled time).

In an email to reader Karl, AT admitted that the performance level is “quite low by some international standards,” but takes account “of the condition of the assets (tracks and signalling equipment) and the age of the equipment (trains).”

Auckland’s Onehunga was once again the best of the lines - 96.8% punctuality (March 96.4%)

Then came:

Western 86.3% (March 85.3%)
Southern 78.1% (March 81.3%)
Eastern 73.5% (March 75.8%)

Auckland’s lines have continued to be affected by station upgrades and pre-electrification work.

Veolia warns that this work will continue over the next 3 months so “at times these works may unfortunately affect services.”

In Auckland in April, there were three major operational issues which affected the service.

  • The first was a train failure on Wednesday April 6 at Papatoetoe which impacted on 67 trains and 15 cancellations.
  • The second issue in Britomart tunnel on Tuesday April we affected a 43 services including 4 cancellations.
  • On April 29, a train being used for overnight upgrade work failed and limited access to platforms at Newmarket affecting 48 trains and causing 18 cancellations.

And 3 network failures caused by signal, points and Central Train Control (CTC) link failure occurred during April.

  • The first occurred between Newmarket and Morningside on April 11, then Papatoetoe on 16 April and Newmarket on 20 April.
  • These combined network issues caused delays to 381 services including 34 train services cancellations.

For April in Wellington: Johnsonville was the best performing - the Wairarapa the worst.

  • Johnsonville Line – 93% on time
  • Kapiti Line – 81% on time
  • Upper Hutt Line – 83% on time
  • Wairarapa Line – 68% on time

New York claims last year 96% of its trains were on time. Melbourne is contracted to be at least 86% punctual. Until this week’s disasters, Tokyo trains aim to be 100% punctual and apologies are made if more than a minute late.




  1. [...] Report from AKT Ninety per cent of Wellington trains were on time to within 5 minutes in April, and 84 per cent of trains were on time to within 3 minutes. [...]

  2. George D says:

    When will it end?

    (The condition of the network being a legitimate excuse for poor performance).

  3. Matt L says:

    My guess is they will keep using it as an excuse up until the end of the electrification works, then while we wait for the new trains to arrive it will be the train are old etc. After we get all of the new trains in they will then find something else.

  4. Ingolfson says:

    Isn’t the fact that the Onehunga Line is best in being on time a sign that it ISN”T assets?

    I am just guessing, but wouldn’t that imply more likely it is the over-crowded network, or unrealistic performance expectations in such a network, so that when something falls over, more than just one thing falls over…

  5. Matt L says:

    Ingolfson - I think the reason Onehunga is on time more than others is most likely due to the short nature of the trips, the other lines are around twice as long so there is much more of an opportunity for delays to come in

  6. [...] of our public transport is still not good enough. AKT last week compared Auckland’s April rail performance to Wellington’s - a city painfully suffering [...]
